CHECK-ROW ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 584,991, dated June 22,1897.

Application filed December 12, 1896. Serial No. 615,469. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY V. DIEHL, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Check-Row Attachmentsfor Corn-Planters, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to certain new and useful improvements incheck-rowattachments for corn-planters.

The general purpose and object of myinvention are to provide anarrangement by which proper relative adjustments may be made of thecenter and the stops on which is mounted and by which is stopped thelever used to operate the seed-dropping devices by the action of knotsor enlargements on the checkrow wire coming into contact with suchlever. This adjustment of said center is for the purpose of bringing thestarting position of the lever to a point to agree with the position ofthe knots on the wire when the wire is adj usted to different placesacross the field, in doing which the knots may not come in line, witheach adjustment, with the place they occupied in the former position ofthe wire, and the purpose of this adjustment of the stops is to causethem to stop the lever at the same relative position with respect to theseed-dropping devices, no matter to what point the center of the leverhas been adjusted.

In the accompanying drawings, on which like reference-letters indicatecorresponding parts, Figure 1 is a plan view of my checkrow attachmentwith the adjacent parts of so much of a corn-planter as is necessary toillustrate the operation and purposes of my invention; Fig. 2, a frontelevation of my attachment with a part of the machine-frame in section,and Fig. 3 a perspective view of the lever-bracket.

My assignee,The Foos Manufacturing Company, which is also the assigneeof James F. Winchell of the invention set forth and shown in hisapplication, filed May 14, 1896, Serial No. 591,462, and patentedJanuary 12, 1897, No. 575,289, has been manufacturing and sell- Myinvention is designed to improve or supplement the said Winchellinvention in the particulars indicated in the preamble above. In thepractical field use of the said Winchell invention it developed that thestops S and T should be adjusted with such relation to any adjustment ofthe center H of the lever Gr as that the stroke of the inner end of thelever in operating the rod L would commence and end at the same points,so that the knots on the wire would be released by the lever at the sametime with respect to the dropping position of the dropping mechanism, nomatter at what point the center H might have been adjusted. It is toprovide for this proper relative adjustment of the stops with respect tothe difierent adjustments of the center of the lever that myinvention isdirected. Accordingly I have devised andapplied what I term alever-bracket, by which the stops are carried. Therefore I employ thesame or substantially the same frame A, carrying the sheaves B, whichguide the check-row wire 0 with its knots or enlargements D through theattachment. This frame A, I bolt or screw to the frame E of the machineby means of an intermediate bracket F, bolted to the machine-frame, asshown at G, and slotted, as shown at H, to receive the bolts I of saidattachment-frame A. A center or pivot J in the form of a bolt isfastened to the frame A, on which is pivoted the lever K, correspond:ing with the lever Gin said Winchell patent and otherwise constructed asin said patent, having a fixed jaw L and a pivoted jaw M, the latterbeing carried on a hinge O and having a lug P, adapted to come incontact with the stop Q to open the jaw and release the check-row wire.The stop Q is for this *purpose, and this stop R is for the purpose oflimiting the other movement of the lever K when drawn upon by the springS, secured at one end to a projection on the hinged jaw and at the otherend to an arm U, fastened to the frame. This spring, as above stated,returns the lever to its position against the stop R and alsoincidentally acts to close the jaws ready to make contact with the nextknot in the check-row wire.

I come now to the lever-bracket, which is shown at V and which ispivoted upon the pivot or stud J along with the lever K and has itsshorter arm V extended along under the shorter arm of said lever K andbifurcated to fit upon a fixed stud \V, projecting from the bracket F.The center of this stud IV is coincident with the center of the pitmanX, where it engages with the inner end of the lever K. Stops Q and R,before referred to, are projections from this lever-bracket V, as aboveindicated. Slots a in the lever bracket receive bolts Z), carried by theattachm ent-frame A, so that the lever-bracket can be fixed and securedin any position it may assume relatively to the frame A. Now let it besupposed that one row of corn has been dropped, that the check-row wirehas been changed to a new position across the field, and in doing so theknots have been shifted a little out of line with the posit-ion theylast occupied. This new position of the knots would cause them to bereached by the lever K a little later or a little sooner, according astheir new position is in one direction or the other out of line withtheir last position. Now the thing to do is to so adjust the lever andits stops Q and R that the lever will meet the new position of theknots, both as to the first contact with the knots and the releasing ofthe knots. In the \Vinchell invention above referred to this is done byshifting the frame A in a right line and shifting the stops S and T atthe same time in a right line while the ends of the lever are shifted inthe arc of a circle and therefore at a different ratio ordifferentially. That was objectionable under some conditions. In mydevice the stops Q and R, like the lever, are adjusted in the arc of acircle and from the same center namely, the center of the stud and thepitman connection with the lever, which become the fixed points of thelever-bracket V and the lever K when the bolts Z) are released and thebolts I are loosened and the plate A shifted in a rightline, carryingthe pivotstud J with it. Thus by means of my loverbracket I adjust thestops Q and R from a common center with the fixed point of the leverduring the time of adjustment. This results in stopping the lever at oneextreme and opening the jaw at the other extremity at the same relativetime in all of the different positions to which the lever and stops maybe adjusted.

The pitman X, with the ratchet-wheel Z,

constitute the operating mechanism for the dropping devices, the latternot being shown.

Inasmuch as the return movement of the lever K by the action of thespring S brings it against the stop R with a hammer-like effeet, tendingto shift the lever-bracket in that direction, I have provided anadjustable stop in the form of a screw V in a lug V on the frame A.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. In a check-row attachment, the combination with the attachment-framesecured to the machine, operating mechanism, a lever connected to saidmechanism and pivoted to said frame, and a lever-bracket having stopsand pivoted coincidently with said lever and held at one endcoincidently with the connection of said lever and said operatingmechanism, said lever-pivot being adjustable to different positions.

2. In a check-row attachment, the combination with the adjustableattachment-frame having a pivot-stud, a lever, and a bracketlevermounted 011 said stud, stops secured to said bracket-lever and operatingmechanism connected to said lever and a fastening for the bracket-levercoincident with the connection of the lever with the operatingmechanism.

In a cheek-row attachment, the combination with the adjustable attachmen t-frame carrying a pivot-stud, a lever, and a bracketlever pivoted onsaid stud, the latter having slots, bolts carried by the frame andfitting in said slots to secure said bracket-lever, stops carried by thebracket-lever, a stud which holds the other end of said bracket leverand operating mechanism connected to said bracket-lever coincidentlywith said stud.

t. In a check-row attachment, the combination with the attachment-platehaving a pivot-stud, of a lever and a lever-bracket pivoted on saidstud, the bracket having stops to limit the movements of said lever andbein g adjustable with said lever.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY V. DIEHL.
